' VEHICLE-TIRE.

To all whom it may concern.-

Be it known that I, EDWARD G. SOHLEI- CHER, a citizen of the UnitedStates, residing at Stamford, county of Fairfield, and State of Conn,have invented new and useful Tmprovements in Vehicle-Tires, of which thefollowing is a specification.

' This invention relates to a vehicle tire in which a plurality of fiatside by side transversely arranged members form the wall of an annulartread to ermit positive traction and prevent skidding or side slip.

The object of the invention is to arrange on the circumference of acasing a number of tread sections composed of abrading substance andfabric adapted to grip the ground in alternate sequence.

The invention comprehends means for securely clamping the tread sectionstogether in compact annular formation so as to prevent lateraldisplacement and circumferential creep.

The invention resides in the novel combinations hereinafter describedand claimed, and illustrated in the accompanying drawings in which:

Figure 1 represents a transverse section v of a tire embodying thisinvention.

Fig. 2 is a longitudinal section of a portion of the tire.

Fig. 3 is a side view of an abrading section.

In this drawing the letter a designates a casing which as shown ispreferably of the clencher type. On the periphery of this casing ismounted a series of sections 6 of tough fabric such as cotton duck. Thecotton duck is rendered water-proof by immersing it in a solution ofrubber cement. Each section has a convexed top a to contact with theground and a concave inner portion (1 shaped to conform with theperiphery of .the casing. Each of the sections is provided with twonotches e one being opposite the other.

Alternate layers of abrading material 7 are arranged between thesections of cotton duck. These layer are of the same contour as thesections 6 and have notches g corresponding to the notches in thefabric. Each abrading section consists of a piece of fabric saturated orinfused with a fine substance such as sand or other gritty materialmixed with an adhesive. The fabric with its gritty sub- Specification ofLetters Patent.

stance adhering to it is water-proofed by a gum or rubber cement asnoted above.

The sections of fabric and abrading sub stance are closely packedtogether with their fiat faces abutting each other. These sections aresecurely held together by means of a metal band it shaped to correspondto the concave inner ortions of the ections. The

band is equipped with rim portions 5 to embrace the lateral portions ofthe sections. The band can be vulcanized directly to the circumferenceof the casing to prevent it from shifting or flying ofl. The ends of therim are bent inwardly to hook or engage the notches in the sections asindicated in Fig. 1. This method of fastening the sections togetherobviates lateral as well as centrifugal shift of the sections relativeto the band.

The diameter of the band is somewhat smaller than the casing so thatwhen the casing is inflated the concavity of the band will frictionallyengage the periphery of the easing, thus. effectively preventingmovement of the band. The casing in practice does not receive its fullpressure of air, so that when a part of the casing is compressed bystriking an obstruction, the other portion will and thereby hug theband. When the tread sections strike a projecting stone'or rut in theroadway, the band will move centripetally and by its transverse.rigidness will compress a large area of the casing, thereby absorbingthe shocks otherwise sustained by the wheel.

As indicated in the drawin the sections of water-proof fabric and arading substance are mounted on a pneumatic casing, but it will bereadily understood that the sections with slight alterations of theconfiguration could be made for a solid tire and directly mounted on tothe rim of a wheel.
